What is the sum of 1/9, 2/3, and 5/18? A. 19/18 B.4/15 C. 12/9 D. 8/20

kari74 [83]

Answer:

19/18

Step-by-step explanation:

The GCF of 9, 3, and 18 is 18.

Each denominator must be multiplied to 18, and as a result what you multiply in the denominator MUST be multiplied in the numerator.

9 * 2 = 18

1 * 2 = 2

2/18

3 * 6 = 18

6 * 2 = 12

12/18

5/18

Add all three fractions together:

12/18 + 5/18 + 2/18 = 19/18
